Well, Tear and Luke, obviously. As for Natalia, she'll need time to move on, and then she might decide to hook up with Guy. They'd make a great couple, but Guy's got his phobia and Natalia is a princess after all...

I thought Dist died, but I guess I was probebly wrong...anyway, I don't Jade hooking up with anyone...he'll probebly go back and serve Peony. I wonder where Luke will go, though...I can't see him taking over his father's estate. As for Tear, she'll go were Luke goes most likely, Natalia will eventually take over the kingdom, Guy will serve Luke or Natalia, depending on if Luke inherits his dad's kindgom, and Anise will become the next Fon Master.

Nah, Anise wont be the next fon master. she did say that she's going to reform the order but not by become fon master, because one can become fon master if one can master that daathic fonic arte.

For the end, i think it's Asch because Jade's expression shows dissapointment rather than relieved. For when Asch says "because i promise to someone", it means his promise to Luke that he will keep live.

I know it's sad, but with the contamination effect, i think the one who survived is asch

For the others, Guy will live as a noble in malkuth, Jade will back also, Anise back to daath to reform the order and for Natalia, i think she could become a queen of Kimlasca.

He is what I think. I've played the game so much to the point where I can put together a solid theory =3

Okay.

Luke Fon Fabre- Luke and Asch have merged and become one. Luke has regained his memories (Even Asch's). He and Tear will probably get married and have a family. He will either return to Baticul or live with Tear in Yulia City.

Gulardia Galan Gardios- Guy will most likely retain his fomer status as a Duke of Malkuth and try to restore the House of Gardios in honor and memory of his lost family. He will probably most likely marry Natalia because during the game he is the one who is mostly comforting her during her time of need. (Scene in The "Inista Marsh" and the scene in "Chesidonia" during the final stages of the game)

Natalia- Natalia will NOT marry Luke. Reason being is because during the scene at "Keterberg" during the time you prepare to go fight Van at the "Absorbtion Gate", she asks Luke to repeat the promise Asch said to her. She then says that she will no longer see Luke as the same person as Asch but a different person of his own free will. She said that she will not hold him down to a promise that was no longer valid. She will become Queen someday of Baticul and will most likely end up with Guy (He gets over his phobia when he saves Anise in "Tataroo Valley" During the day when she chases after a Blue Gorgnhood Swallowtail)

Anise- She will reform the Order of Lorelei and will end up as the first female fon master. She will probably also marry Florian. (Seeing how she fell in love with Ion)

Dist- Will probably stay in jail...

Jade- Will return to his life in the military and might rise in the ranks. He will also continue is research on Fomicry to raise the level status of replicas.

That's my theroy of it.

in the nebilim side quest dist was killed by nebilim...so he won't be in jail...

Nah, Anise wont be the next fon master. she did say that she's going to reform the order but not by become fon master, because one can become fon master if one can master that daathic fonic arte.

But Jade ended up smiling.and you know how Jade can see through things(such as lies).and u do have a poimt about Asch and Luke' promise.but the sword was held like Luke's and the hair color(brightER red) was the same as Luke's.and Asch died(but replicas and originals can steal each other's bodies >__>...).And Luke promised Tear that he would come back.

Anise will go with astor the riches man in the desert lol...
Guy will still be a guy.................. or maybe he'll go for general cecile if you did the side quest about gen.cecile and frings you'll understand why...
Natalia luzu kimlasca lanvaldear (that was long) probly lead kimlasca...
The last scene on the game Luke did return.. the place is hod.. he even says this place has a nice view of hod.. and also a promise to someone.. if Luke and Asch merge together and the memories of childhood of Luke will return... he did promise to Tear but he made a promise to Natalia also... we know its Asch but if they merge argg this is messed up... or Luke will gave his life to lorelei to save Asch becz he knew that Replicas shoudnt exist.. umm that was pretty sad ending for the anime series..
About Jade.. did you guys remember the last scene when they all looked to Luke just before we see his face..
The screen zooms to Jade and his face was kinda dissapointed.. just like yamato21 said but knowing Jade being insightful...This bothers me well.. or mybe its just my imagination...

After thinking all these ive got my final conclusion... i'll go for the contamination effect.. remember the cheagles in the cave... when the other one survived and the other died.. the replica tends to be inferior to the original.. wel for the case of Luke and Asch being perfect isofons.. Jade said that something different can happen to perfect replicas...

Luke-he surpassed his orginale (Acsh) so I believe it is Luke in either his own or more likey Acsh body (they exactly the same so who cares). Going to make nice little family with Tear probaly(or else...)
Tear-Be a mother of 2 or 3 depends on how hardworking Luke is, will sing in her beutiful voice, may improve her cooking.
Guy- I see a potential 40year old virgin if he doesnt get over his phobia, if he does he's going to be one-hellava of player
Jade-forgive me but I see him as stand up comedian or the like, just cause of his antics, maybe an uncle to LukexTear's kids*shiver*
Natalia-greive for Acsh her entire life, but wont fail as Queen
Anise-fon masters Floreine's mothe-....i mean advisor

Uhh... ya probly be luke and tear in the end... (luke and asch and tear i guess? whatever the luke/asch hybrid with tear). I really however dont think itd be guy and natalia... and i dont think it would be good if they did get together. I dont think jade will ever find true love but will enjoy tormenting the king for the rest of his days ^^;. Anise might fall in love with floreine maybe... if not just look afte him forever. Guy will prbly be a ladys man for the rest of his days but i dunno if he could ever find the one XD. Natalia.... mnight just get married for sum political reason i think... If not then just rule and enjoy her life.

hey check this out...
watch the scene where Anise and Jade talks about what will they do after the final battle..
Jade will research fomicry again.. and return to the military
Anise will become the first female fon master..

Fighting the optional boss (N*******) on the hardest difficulty takes FOREVER. Your levels won't matter, you have to do a ton of farming rare items to boost your stats or else you will only do 1 damage a hit...

And I do believe that Guy gets over his phobia, because at the end of the game when he sees the clone of his home, he remembers what happened to him. The first step to recovery!

Eeet!! Wrong answer!! Only true fanboys/girls of this would know the truth...

Spoiler Alert! Click to show or hide

There is a side quest with Star, the cheagle found in the cell when playing as Asch. When you talk to Star, he'll tell you that the replica died, but HE is the replica in the originals body. He remembers dying, and then pushing the soul of the original out of it's body. Asch has too much pride, so he doesn't want to kill himself for Luke's sake. However, when he is stabbed, instead of trying to save himself, he finally let's him self die so that Luke can live on. When Asch's arm twitches in the final cut-scene, that is when he is entering Asch's body. Also explains why his hair is darker and longer. Also, Luke is no doubt left handed, while Asch is right handed. Luke's sword handle at the end of the game is facing his left.
Also, it's almost confirmed that Guy and Natalia are a couple. In the final cinematic, Natalia refers to Luke's Coming of Age ceremony at the Duke's manor. Tear responds, "I'm not intrested in some ceremony...In front of Luke's grave." And then Anise, says, "But that's why...the both of you came here, isn't it?" to Natalia. Guy responds for her, hinting that they are together.
Also, Jade's eyes aren't red anymore, which tells his his Fonic Sight has been removed.

I got most of it from a friend, but noticed some of it on my own too.
Read at your own risks...though you've most likely already beaten the game.
